SPINNING AND WINDING MACHINE.

Specification of Letters Fatent.

Patented Feb. 9, 1909.

Application filed May 29, 1906. Serial No. 319,390.

A To all whom it may concern.

Be it known that we, ALFRED J. FoULDs and HENRY A. FoULDs, citizens ofthe United States, residing at Lansdowne, Pennsylvania, have inventedcertain new and useful Improvements in Spinning and Winding Machines, ofwhich the following is a specification.

Our present invention relates to further improvements in the type ofmachine, for simultaneously twisting yarn and winding it into cops,which forms the subject matter of Letters Patent of the United Statesgranted to us on the 29th day of November 1904 and numbered respectively776,128 and 776,129 and also an application filed by us on the 2nd dayof February 1905 Serial Number 246,132. In devising the presentconstruction we have aimed to further simplify the construction andincrease the efficiency, to reduce friction, to avoid as far as possibleall danger of oil or lubricant from the bearings coming in contact witheither the slubbing or cops, and to render the cop builders moreaccessible.

With these and other objects in view the invention includes the variousfeatures of construction and arrangement of parts hereinafter describedand particularly pointed out in the claims. 7

The invention is illustrated in the accompanying drawin s in whichFigure 1 is a ongitudinal sectional elevation of a suflioient portion ofthe machine with a portion of the center broken away and, Fig. 2 is avertical. section taken at right angles to Fig. 1 looking towards theright. Fig. 3 is a side elevation of the up erportion of one of the topmembers on a argerscale with parts sectioned to show the splined groovesand with the thread guide carrying ring 30 and bar 31 in section. Fig. iis a horizontal section through the upper portion of the cop buildershowing the ring 30 and bar 31 in plan.

In this drawing we have shown in Fig. 1

only the extremities of the machine with the central portion brokenaway, but it willbe understood that the machine can be built of a lengthsufiicient to accommodate any desired number of spindles, by makingit ofthe appropriate length.

Referrin by reference characters to the drawings the numerals 3 indicatethe side frame members of-the machine to which is.

suitably secured, the lower member 5 of two cross bars or members 5 and6 in which are journaled the cop builders and upper parts of the mastercontrolling devices in a manner hereinafter described. The member 5 isprovided with a vertical flange 5 upon which the bar 6 rests leaving aspace between in which are located the spiral gears 8 which operaterespectively the master controlling devices and the cop builders. Theportions of the members 5 and 6 which lie in rear of the cop buildersare formed semi-circular in cross section, providing between them acylindrical gear chamber in which are located the spiral gears 11mounted upon the longitudinal drive shaft 12 and meshing with the spiralgears 8. The gear chamber forms also an oil chamber so that the gearsmay rotate in oil or grease efiecting a great reduction in friction andconsequent saving in wear and tear.- Each gear 8 of the cop builders issecured to a barrel 13 which is rotatably mounted in suitable journalsor bearings in the bars or members 5 and 6. The barrel 13 extends abovethe member 6 and to its upper end the cop builder 14 is connected in anysuitable manner. Thus the cop builders project upward above theirsupporting and operating parts making them more readily accessible andholding the cops above the gearing and in such relative position that nooil or dirt from the machine can be thrown upon the thread or cops.

In suitable bearing brackets 15 in the lower part of the frame isjournaled a horizontal member or bar 16 having a semi-circular channeledportion 16 and flanges 16 and 16 upon which rests a top bar or member 17havinga corresponding semi-circular channeled portion 17 forming a gearchamber 11 similar to the upper chamber above described. These bars 16and 17 carry suitable bearings in which are journaled the hubs of thespiral gears 18 which mesh with the spiral gears 19 on the longitudinaldrive connection so as to be vertically movable through the hubs whileat the same time they are rotated thereby, the spindle ex tensions eachcarrying a spindle 23. The spindles are designed to be held elevated l ysuitatle counter weights in substantially the manner hereinafterdescrilted.

The slubling is led from suitable cams or containers which may belocated at any convenient point and which are omitted from the drawingfor clearness of illustration of other parts. Thence it passes over afeel roll 24 extending the entire length of the machine to which apositive movement is imparted in the manner hereinafter described. Fromthis roll each sliver passes to and between a pair of guide rolls 26'and27 carried by adjustalle brackets 26 and. the latter of which is held incontact with the former preferably by gravity. From these guide rollsthe slivers or slnbtings are led downward through the rings 28 to andthrough thread guides 29 and thence through vertical slots in the copl;uilders 14 to the spindles 23, around which they are wound by the morerapid motion of the cop l uilders.

Each thread guide 29 is carried ly a 30 which has one or more pins orprojections 30 engaging vertical grooves in the cop builder so thatwhile the rings are capa le of vertical movement with relation to thecop builders they are compelled to rotate in unison therewith. The rings30 are rotatal ly mounted in a longitudinal bar 31 which is connectedwith thread guides and caused to rise and fall to impart the necessaryvertical movement by the master devices 32 at the ends of the machine.Each master device is constructed in sul' stantially the same manner asin my aforesaid patents and while a specific description thereof wouldseem unnecessary it may lie briefly descrf ed as follows.

To an extension of the lower end of each upper end gear 8 is secured aframe or casing 33 in the side of which is ournaled upon a horizontalpin or axis a vertical level gear 34 which has a crank pin 35 projectinginto a horizontal bearing slot at the lower end of a shaft or red 36.This shaft or rod projects up through the tnl ular hub and at its upperend is provided with a rotata le but non longitudinally mova leconnection with the liar 31 uhi h carries the thread guides as at ovedescriled. Thus as the gear 34 rotates the crank pin causes the shaft orrod 36 to reciprocate vertically and effect the rising and fallingmovement of the thread guides. The gear 34 is caused to rotate l y thebevel gear 37 jonrnaled in the lower part of casing 33 and connected l'ysuitalle 'liexilile shafting 38 to a shaft section having a splineconnection with the hub of the lower end gear 18. As the gears 8 and 18are driven at different rates of speed it will be obvious that thisdifferential ring.

motion will, through the connections and bevel gearing above described,effect the reciprocation of rod 36 and consequently the verticalmovement of all the thread guides.

As the horizontal member or bar 16 is mounted to rock in the learings 15it mu be tilted to swing the upper ends of the spindles forward out ofline with the (op builders after the cops are finished and the spindlesdepressed so that their upper ends clear the lower edges of the hui s ofthe upper gears, the tilting being assisted h weighted arm 16*.

'lhe particular means hy which the spindles are normally yieldingly heldelevated and the lowering to remove the cops will now be described.

In the lower part of the machine at each end is pivoted a lever 38 thefree end of which is connected by a spring latch 3t) with the bar 40 inwhich the lower ends or" the spindle extensions are join-nailed 'l hisbar is vertically movable in the swinging guides 41 which depends fromthe bar 16. A cord or band 41 connected to each lever 38 passes upwardover pulleys l2 and 43-; and carries at its other end a weight 44 andthus these weights tend to draw the lever upward and through the latch39 to press the bar to and consequently all the spindles upwardly. 'lheweight of a large number of spindles is quite considerable and consepiently the counter weights must be uite heavy. ln order to enable. themto be. lowered conveniently and easily a link 45 is pivotally connected.to each lever 38 and is provided with a slot 46 engaged by a crank pin-17 on a gear 48. Each of these gears 18 is in mesh with a smaller gear19 carried by a shaft 50 extending lengthwise ot' the machine andprovided at one end with a hand wheel 51. By this hand wheel the gear 48 may be rotated to cause the crank pin to force. the link 45 and lever38 down into the position shown in Fig. 2, at which. time the crank pinbeing in line with the pivot of the link and. the axis of the gear thelever will be locked against upward movement. l he guides 41 and sliprail or bar -10 may now be swung rearwardly to swing the upper ends ofthe spindles outwardly for removal olthe cops, the latches being therebydisengaged from bar 40. A hand lever 52 is provided for effecting thisswinging movement. After the cops have been. dolled the spindles areswung back and the hand wheel .31 rotated to bring crank pin 47 into adiametricalhopposite position, the weight raising the bar 38 so that thepin remains in the bottom of the slot. In this position the spindleswill be in position to begin the formation of the cops and the length ofthe slots 46 is such as to permit the spindles to be lowered during theformation of the cops.

Asa convenient means of o crating the feed roll 24 we may provide t efollowing mechanism. The roll has at each end a gear 24 which mesheswith a gear 25. Rocking arms 53 on opposite sides of this gear carry 0positely disposed pawls 54 which engage t e teeth of the gear. Thesearms 53 are connected by rods 55 with a pivoted arm 56 which isconnected by a rod 57 with the bar 31. Thus as the bar moves verticallyto move the thread guides the feed roll will be rotated and at a'speedcorresponding to the speed of the feed guides.

When the machine is used for spinning asbestos covered wire the spools58 carrying it will be mounted on a rack 59 as shown.

The main drive shaft is shown at 58 carrying step pulleys 59 over whichpasses belt 50 running to any convenient source of power. From thisshaft the motion is transmitted to the shafts 12 and 20 by suitablebelts and pulleys as indicated in dotted lines. The relative size ofthese is such that the shaft 12 as above ex lained, rotates faster thanthe shaft 20 andPthe system preferably includes a system of cone ulleyswhereby the relative speed of the sha ts 12 and 20 may be varied toimpart more or less twist according to the requirements of the work.

Many mills desire to run a large number of spindles, but as only acertain number of spindles can with any degree of practicability beembodied in a single machine where a larger number are required a numberof machines may be set up end to end. Where this is done we prefer toconnect the operating shafting of the successive machines or sections byclutch mechanism and to control the relative speed of the upper andlower gear shafts by a single master or speed controlling device ordifferential gearing.

In our prior patents we have contemplated starting the wind on the barespindle. Such an operation required an automatic speed changing deviceto vary the speed at starting until the thread had been wound on thespindle up to the full diameter of the cop. We find that such anautomatic device can be dispensed with by the use of a starting cone 2-3covered (preferably) by a removable cone 23 of paper or like materialwhich is removed with the cop and remains therein until the cop has beenused, after which it may be brought back to the machine for use overagain. With such a device the full length of thread is drawn at each lapat the beginning of the wind, and yet there is no danger of collapse ofthe base of the cops after removal from the spindles.

Having thus described our invention what we claim is 1. In combination,a main frame having a supporting member, tubular hub members journaledin said supporting member, cop builders carried by said tubular hubs,spiral gears on the hub members, a longitudinal shaft having spiralgears meshing with said first named gears, a rocking frame pivoted inthe lower part of the main frame, a plurality of spindles rotatablymounted in said rocking frame, and capable of vertical movement therein,spiral gears journaled in said rocking frame, and having a splinedconnection with the spindles, a drive shaft with spiral gears thereonmeshing with the spiral gears of the spindles, and yielding means fornormally holding the spindles elevated with their upper ends projectingthrough the cop builders, substantially as described.
